Paul,
Very sorry for not getting back to you sooner. Yes, sandbox mode would prevent users from registering on your site. That's not something that the Autotune tool can alter, so it's something you would have had to set. I'm glad you found it though. The privacy policy is required by Facebook, but not something that would prevent registrations. So, it's good to have (to fit their requirements), but they don't currently limit apps that don't provide one.

brijeshsapple,
I responded to your other post about this issue earlier in this thread . If you are still having issues, definitely check the sandbox mode setting, try again, and post back to that other thread so we can help further.

Thanks,
Alex
